How can I use firebase Phone Number Authentication with react native?

Can someone please tell me simple steps of putting firebase authentication in a react native application? I am a pure react native developer and never have done any of those safetyNet setup or reCaptcha setup in Android, can someone please show me simple steps of using phone number to send confirmation code in firebase? and how can I create user with phone number with firebase like createUserWithEmailAndPass() of firebase?
